Young & Wild by Brooke St. James

The golden boy meets his match in the Tanner Family series finale.
Tanner Wilde was just that. Wild.
He had been working hard and playing harder for so long that he paid no mind to the long line
of heartbroken women he left in his wake. His life seemed full, and he was nowhere near ready
to settle down.
Jillian Young was just the opposite.
She was solid, stable, and content with the quiet life she was building for herself. Everything was coasting along until the night Tanner Wilde showed up on her doorstep. Even though they had been school mates for years, he still had no idea who she was.
That was fine with her because she wanted him to get out of her life as quickly as possible.
This is the story of how that didn’t happen.
